Substrate: acidic soil (mostly on siliceous substrata)
Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
Note: a species with a thick, cartilaginous, rugose-plicate to bullate, yellowish white thallus forming small pillows, large, adnate, confluent, black apothecia which are first flat and thinly marginate, then convex, a brownish epithecium, a pale hypothecium, coherent paraphyses, 8-spored asci, and simple, hyaline, ellipsoid ascospores measuring c. 18.9 × 13 µm; only known from the type collection and from a few localities in the mountains of Central Europe, this taxon deserves further study.
